Which type of inhibitor increases the apparent Km without changing Vmax?
Answer and explanation
Correct answer: B. Competitive inhibitor
- Step 1: A competitive inhibitor binds the active site, so more substrate is needed to reach half Vmax, but enough substrate overcomes it. Answer: Competitive inhibitor. Why not the others: Noncompetitive inhibitors lower Vmax, uncompetitive inhibitors lower both Vmax and Km and mixed inhibitors change both.
